  <dc:description>Based on ${e}^{+}{e}^{-}$ annihilation data samples collected with the BESIII detector at the BEPCII collider at 13 center-of-mass energies from 4.008 to 4.600 GeV, measurements of the Born cross section of ${e}^{+}{e}^{-}\to p\overline{p}{\pi }^{0}$ are performed. No significant resonant structure is observed in the measured energy dependence of the cross section. The upper limit on the Born cross section of ${e}^{+}{e}^{-}\to Y\left(4260\right)\to p\overline{p}{\pi }^{0}$ at the 90% C.L. is determined to be 0.01 pb. The upper limit on the ratio of the branching fractions $\frac{B\left(Y\left(4260\right)\to p\overline{p}{\pi }^{0}\right)}{B\left(Y\left(4260\right)\to {\pi }^{+}{\pi }^{-}J/\psi \right)}$ at the 90% C.L. is determined to be 0.02%.</dc:description>
